Frame Relay Standards - HP auroraTempo User Manual

aurora Tempo - User Guide
With Frame Relay, data within the network is statistically
multiplexed, so any unused bandwidth may be allocated
on an 'as-needed' basis.
This ability to accommodate sudden traffic bursts by
utilizing available bandwidth makes Frame Relay more
flexible and cost-effective than TDM solutions.
Furthermore, data is only submitted to the network when
there is 'real' data to be sent (i.e. not just idle 'sync fills'),
thus resulting in greater network efficiency.

Frame Relay Standards

Initially, the two organizations responsible for the
development of Frame Relay standards were the ITU-T
(formerly the CCITT) and ANSI. The ITU-T is composed
of members from international telecommunications
carriers and vendors. ANSI is the US standards body
which has many committees, one of which is responsible
for telecommunications standards.
However, these standards were taking time to be written
and ratified so their development was spurred on by a
group known as the Frame Relay Forum. The Forum was
formed by a number of key vendors who first came
together to ensure the interoperability of their products.
The Forum's charter is to promote the acceptance and use
of Frame Relay and to assist in the formulation of the
international standards.
ANSI, driven along by the Frame Relay Forum, were the
first to agree their standards. The CCITT specification
quickly followed and has many similarities to that
produced by ANSI.
